Comprehensive Technologies International, Inc. v. Software Artisans, Inc., 3 F.3d 730 (4th Cir. 1993) was a case in which the U.S. Court of Appeals for the Fourth Circuit discussed legal tests for software copyright infringement, and ruled that trade secret misappropriation requires more than circumstantial evidence. The case also ruled on what terms may be reasonable and enforceable in non-compete agreements.
